Click the images for bigger versions. Note the smooth color gradients and custom textboxes I've implemented for some of the games. Although these images are all in fullscreen mode, you can turn on the viewframe in all games, if you prefer. The screenshots were taken at a simple 2x internal resolution, but the engine can handle any resolution you want, up to and beyond 4K.
Eden no Kaori (JAST, 1996)
A murder mystery at a mansion, starring Joe the private investigator. Much less compulsive verb+nouning than in the earlier games. Some two dozen different characters, more than one ending.
Status: Not completable, clickable map not implemented yet. Ending script missing, graphics need polishing.
Shyuukan From H (JAST, 1997)
I have no idea what's going on in this game, but it looks funny.
Status: Not completable, clickable map not implemented yet. Intro and ending scripts missing, graphics need polishing, script needs to be localised. Music file conversion is not perfect.
Majokko Paradise (Tiare, 1996)
This is the game I'm maybe most excited over. As far as I can tell, it's like Season of the Sakura but with magical girls. It's set in the same school. You even get some cameos, and the cast performs a nice song in the middle of the story.
Status: Probably completable. Intro and ending scripts missing, graphics need polishing, screen scrolling effects missing, script needs to be localised.
Setsujuu ~ Yuganda Kioku (JAST, 1995)
A student goes on a ski resort trip with his childhood friend and a few others. They meet many interesting people while behaving badly.
Status: Completable. Graphics need polishing.
Tasogare no Kyoukai (Tiare, 1997)
Our protagonist, possibly a student/archeologist/treasure hunter, arrives at a remote village in a quasi-modern setting, and meets the locals. Bad stuff happens, and only you can save the missing girls from a first-person view dungeon! No RPG elements, but yes multiple endings.
Status: Not completable, needs a clickable map as well as a first-person view mode. Ending script missing, graphics need polishing, script needs to be localised.
Transfer Student (JAST, 1995)
Don't confuse this with the completely weird localisation by the same name. This is the original version, presented as a proper verb-noun visual novel instead of that daydreaming mess with an excitement meter.
Status: Probably completable. Ending script missing, graphics need polishing.
In addition to these, there are a few more titles with partial support:
Vanishing Point (Tiare, 1995) is an adventure/JRPG hybrid, allowing you to freely roam around a top-down view of the same town Tiare's other games take place in. Has a great, if short, soundtrack. Needs serious rebalancing to be fun.
DEEP (JAST, 1994) is a point-and-click adventure with first-person combat and a rocking soundtrack. The scripts are similar to the other games, but I can't figure out where the drawing commands come from. Just as well, since the majority of the graphics are ugly digitised photographs (including a few that I can't seem to decompress correctly). The combat is slow, boring and unbalanced. Then again, you can choose to play as one of four characters, who each have unique commentary on everything as you play, and they get different encounters. If the battle system was replaced with a fun minigame, this game could be of interest.
Super Ultra Muttin Puripuri Cyborg Maririn DX (JAST, 1994) is also an adventure with first-person combat, with a decidedly wacky bent. I have the older scripting format only partially worked out.
Tenshitachi no Hohoemi (JAST, 1996) is a dating sim, kind of like True Love, complete with chibi animations, only you already failed at school and instead are tutoring three girls, trying to get their statistics high. The new interface is the main problem.
Muchimuchi Sekushii Pafe (Tiare, 1998) is already a Windows-native game, with various familiar locations now available in re-colored versions. The engine is very similar to their earlier games, but various argument sizes in the script language have been doubled and there's a new, more colorful graphics format.
Nocturnal Illusions and Mayclub – I can extract the graphics and music from the Windows and PC98 versions, but there's no point adding further support since the highly polished remakes already run smoothly on VileVN.
In addition to all those, I have a potential list of some three dozen other PC-98 games by various companies that appeared particularly interesting and would be awesome to support. This includes games by Abogado Powers, AIL, Cat's Production, Cocktail Soft, Fairytale, Four Nine, Janis, May-Be Soft, Melody, Silky's and Umitsuki Productions...
